Office for iOS & Android
/Free, but it requires a Microsoft account, and only allows viewing (which iOS already does, without a Microsoft account). And if you want "basic editing" it'll cost $4/month. Or, if you want more advanced editing you can just buy the whole iWork suite for $30 in the App Store. This sounds like the stupidest thing ever. How did it possibly take Microsoft 4 years to come out with this?
